Specication of Letters Patent. 4 Patented Jan. 14, 1919.

Application :nea :une as, 191s. serial No. 242,549.

To all whom t may concern.'

Be it knownthat I, MAX KRAUss, a subject,`

ofthe King of Bavaria, having resided in the United States one year last past and having declared my intention of becoming a citizen thereof, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Talking-Machine, ,of which the following is a specification.

My invention relates to the general class of talking or sound-reproducing machines which play records in the form of flat disks, and has for its primary object the construction of a machine in which va -plurality of records, either single or double-faced, and of any desired diameter, can be set up, and any one of them, at the selection of the operator, be played.

My invention embodies improvements upon a talking machine invented by and'patented to me under United States Letters Patent, No. 1,199,192, dated September 26, 1916, and its object 1s to enable me to remove any one of the disks without as in the construction of my patent being under the necessity of removing a given number or assemblage of them.

In other particulars this invention is characterized by the general features and advantages of my patented machine in that it is a mere matter of dimensions as to'what number or diameter or character of disk records it can play.

My present machine, moreover, is adapted for use with any form of sound box, the stylus of whlch can operate upon either the up-and-down tone groove of the type of the Edison or the in-and-out tone groove of 40 the type of the Victor machines, only one operator to; at wi select an pla anyone of any) desired number of records W ich happen to e set up in the machine.

The machine, moreover, is capable of being operated 'by any 'preferred type of motor, mechanical or electrical.

With these primary ends in view and for the purpose o the construction of an mexpen'sive, mechanically simple and durable.

machine, I have resorted to a construction which I have hereinafter explained, for the ing shown a mac ine adapted to operate with a double group or series 4of live records each, all in vertical disposition, although of v the purpose` o necessar lto .y enable the" matter of the proportioning of the machine and the duplication of certain parts herein? after described, to adapt the machine to play a much larger number of records than five. In the accompanying drawings I have, for illustratingmy invention,

shown a certain type and embodiment of twhich is at present preferred by me, because in practice it has given satisfactory and reliable results.

lIt is to be understood, however, that the various instrumentalities in which my invention is embodied can be variously arranged 'and organized and that my invention is not therefore limited to the precise arrangement and organization of such instrumentalities as are typified in the construction illustrated in the accompanying drawings and herein described.

In the accompanying drawings:

Fi re 1 represents 1n top plan so much of a tal lng machine embodymg my invention as -is necessary to illustrate it.

Fig. 2 represents in side sectional elevation on the dotted line 2--2 of Fig. 1, the machine of Fig-1, certain of its lcomponent instrumentalities being shown in side elevation. Fig. 3 is a fragmentary side view upon an enlarged scale, of one group of records partly in section and partly in elevation, the

sight being taken on the dotted line 3'3 Fig. 4 is a fragmentary end elevation on the line 4--4 of Fig. 2; and

Fig. 5 is a. fragmentary side view of a modification. .y

Similar numerals of reference indicate 'corresponding parts;

ments, the upper of which I designate 3 and vthe lower 4. purpose of simplifying the description, havby the number 5 and which in the construe-- f tion shown are composed of two disks, presumably one-faced disks, spaced 51de by grooves upon their 4mounted. and from which they are removmounted the disk-carrying able in separate parts, and referring now to Fig. 3, I have designated the separated parts yor sections of the shaft as 61, 62, 68 and 6*, which as will be apparent are mounted. in separated boxings or bearings 71, 72, 7s and 71 respectively mounted upon standards 81; 82, 82,. 84 erected fromv the partition 2 of the casing.

This partition 2 is formed with a ntral circular aperture 9 and over this ieprture, concentrically with respect to its ter, 1s plate 10 which itself vis circular and of slightly greater d1 ameterthan the aperture in the partition,

l -over and with respect to which it is mounted and rests free to be rotated o'r turned by having its o uter edge overlap and rest upon a circular track 11 on the partition, with respect to vwhich it, said late, and the standards, bearingsfand sha s, and records which it carries, are adapted to be turned so as to completely transpose the positions of the disksA relatively to the soundbox, not shown.

The shaft as an entirety, that is to say, the divided parts ofv it, indicated, fas explained, by the numbers 61 to 6*,-is mounted upon two shaft su ports 12,' 13, fastened `to-andspringing`- rom the disk carrying plate 10 near the ends of a selected diameter of said pla te`, and 1s mounted for rotation in bearings 14,15, on said supports;

y -The disk .carrying platel() is formed with a series of parallel slots 16, Figstl and `3, through which the records'and'the record' clamping disks'17 and 17 pass s'o that, segments ofthe records pass` down into the y lower compartment and counterpart seg- A'r-fthe outer end ofthe' bracket' 19V 'and thecons Inectio'n of the v'plate 10 Awith the pivotglS] Apreferably by ,ineans' of 'a sleeve 22 oon- .'iso.

Lampara?l isnconnectedwith anotched pin 25 on the end of a supplemental or driving shaft 26 mounted in a bearing 27 erected on a standard 28 springing from the partition 2. The end of the driving shaft beyond the notched end is equipped with a toothed spur-wheel 29, which passes downward -through a slot 30 in the partition 2 into the lower compart ment 4 of the casing, and is therein adapted tobe engaged with and operated by a pinion, not shown, but supposedly connected with any suitable motor, also not shown. The periphery of the disk carrying plate 10 is provided with two notches 31, 32, diametrically opposite to each other, and either of which is adapted to be engaged by a lockingplate 33, provided with a thumb screw 34, on the partition 2 in such posifl tion radially toward the circular plate 10 l as to be adapted to engage within leither one 8'5 of said notches 31 and A32 and thereby hold the shaft as van entirety of the plate in alinement with the driving shaft 26,--whether said shaft be in the position shown in Figs. 1 and 2,-or in the precisely reverse posi'- 'tion, 'not of course shown, which it would assume when the .plate and all.0f its adjuncts are lifted so as to disengage the notch atan end of the shaft from the driving shaft and permit of the complete turning'95 around of the plate and records to presentY Y the opposite sides of said recordsto the@ stylus of the soundbox In. order conveniently to apply and re`. move any one of the records 'from the shaft,

Obviously, these leftfhand clampingvdisksinthe assemblage of the pms. wat@ smily wah the sections, of' Each semen bf th; ninfa-'taking 'frf ex- 1 g. 3, is internally-j g toia suiicie'nt dis-1 1 35, which is inserted between the inner en other and jlo'n tud-inail extending; a cerf f tain' distance t rough..` 'eilfs'haft section, in

From this construction, it will 'be apparent that in order to apply a record to a given pair of clamping disks and so to the shaft, the slidably movable disk 17x is adapted to be moved to the right, as shown to the right-hand side of Fig. 3, with the result through the action of the pin 36' of compressing the spring 35; The disk 17x will then have moved a suiiicient distance to the right to permit of the moving ofthe record` likewise to the right and o' the right-hand end 63 of the shaft section to permit of the clearance of the record and its taking out of the machine.

In other words, the central record shown in Fig. 3 is clamped between the disks 17 and 17* when said disks are brought' together by the left-hand movement of the disk 17X, the spring 35 holding said`disk in its then clamping position,-whereas in the view to the right of said Fig. 3, the clamping' disks have been separated, the spring compressed, and the record cleared so as to be removable.

This in and out movement ofsone of the clamping disks is intended to be accom-v plished by hand by for instance taking hold of the pin 36 and moving it to the right to compress the spring and let the record be free, or permitting it to be moved to the left to clamp the record against the other disk 17 when the central hole in the record has been slipped over the end of the shaft section 63, as shown with respect to the central record of said Fig. 3. Obviously, either one of the clamping disks may be provided with a spring, and obviously also, if "desired, the sprin instead of being entered. within a bore in the shaft section, may be mounted so as to surround an extension 8x of, for instance, a standard 83,'as shown in Fig.'5.

38 are a pair of lugs or other projections either separately applied or in the form of a transverse pin, which are mounted upon the hubs 172 or 8x in the construction of Fig."5, which when the clamping disks are so closely assembled that it is hardto'reach them with ,the -ingers, make it possible to eii'ect the movement of the movable clamping disk by the `use for instance of a Spanner.

Having now described a convenient con.- struction typically embodying my invention, it will be understood that in its use I am not limited to any particular number or any diametric size of record, as either the usual ten or twelve inch sizes may be used.

It will be further understood that .While the construction described enables me with ease to apply and remove the desired numy ber of records, the entire groups can be easily reversed by the reversal lof the disk carrying plate withoutv the independent re moval of any one of the records,-that vaxially coincident with the center o to say, after I have assembled the records which I desirel to use in for instance the two groups represented, I can, by the turning of the disk carrying plate, reverse both groups together, or, if I desire to reverse only one of the groups, lift its shaft up I claim as'new and desire to secure by Letters Patent, is :f-
